Patented Oct. 20, 1936 PATENT OFFICE VENTILATING AND SIGNAL WINDOWCONSTRUCTION I John F. Levan, Elkhart, Ind., assignor to Excel CurtainCompany, Elkhart,

of Delaware Ind., a corporation Application August 29, 1933,- Serial No.687,339 1 Claim. '(c1.'296-'-44),

This invention relates towindow structures,

particularly window structures for motor vehi-' cles, and the like,which are capable of being raised and lowered.

It has for its object such a window embodying a sash pivotally mountedon an upright axis to swing laterally into and out of different inclinedopen positions for the purpose of controlling the ventilation throughthe window, and also for'the purpose of providing an opening forsignaling other vehicles through the window, and when in its normalposition is capable of being raised and lowered. V i It further has forits object, a particularly simple and easily operable mechanism forholding the pivoted sash in any one of its adjusted positions.

It further has for its object, a holding mechanism which is located in ahollow member, or rail, of a main frame, or sash, supporting the pivotedsash, and a holding mechanism of such construction, that it can belocatedin such a confined space, and at the same time be readilyoperable.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawing in which like characters designate corresponding parts in allthe views.

Figure 1 is a fragmentary elevation of a structure embodying myinvention.

Figures 2 and 3 are detailed views of a mechanism for holding thepivoted sash in its adjusted position.

Figure 4 is a sectional view taken on line 44, Figure 1.

I designates a suitable hollow body which may be the door of a motorvehicle, or the portion of the door below the belt, or may be a portionof the vehicle body.

, 2 is a sash capable of being raised and lowered into and out of thebody I. This sash includes a marginal frame usually formed up of sheetmetal having tail pieces 3 extending into the body I and coacting withguides therein. The sash is capable of being raised and lowered by anysuitable window raising and lowering mechanism.

In the illustrated embodiment the sash 2, in addition to a marginalframe, includes a glass pane l which partly fills the space enclosed bythe frame 2, the glass pane 4 being here shown as filling substantiallythe rear half of such space,

and also includes a movable sash member 5 fillhalf of such space. Thesashmember 5 is pivoted on an upright axis to the upper and lower railsof the sash frame 2 in order to swing, from its normal closed position,that is, when it is in the general plane of the sash frame 2, outwardlyinto different inclined open positions, the pivotal axis being locatedtoward the front edge of the sash member 5 so that when the sash member5 is swung open, it forms a relatively narrow front inlet air opening,and a Wider rear outlet opening.

By sash is meant either a glass pane mounted in aframe, or a partialframe, or a glass pane Without a sash frame. However, in the illustratedembodimentof my invention, the sash member 5 is provided with a marginalframe 6. The sash member 5 is pivotally mounted in the sash frame 2 bytrunnions land 8 projecting from the upper and lower rails of the sashframe 6, these being mounted'in suitable. bearings in the upper andlower rails 9 and II] of the sash frame 2. The rear stile of the sashmember 5 is also formed with suitable weather stripping for coactingwith a'muntin I2 at the front end of the glass pane 4, for sealing .thejoint between the sash member 5 and the glass pane 4 when the sashmember 5 is closed, The sash 5 is also provided with a flange II on therear stile or at its rear edge to lap the muntin.

By this construction the pivoted, or ventilating window, can be loweredand raised into and outof the body I.

The means for holding the sash member 5 in its normal closed position,and in any one of its adjusted, or angular positions, is located in thebottom rail ID of the sash 2. This rail II] is formed up of channel ironwith the channel facing upwardly. The means for holding the sash member5 in position is operable by a handle on the outside of the bottom railI0, and so located thatit can pass up and down through the slot in theupper edge of the body I through which the sash frame 2 moves.

In the illustrated embodiment, of my invention, the locking meansincludes ratchet mechanism including a part mounted on the lowertrunnion 8 within the hollow rail III, and a part movably mounted in thehollow rail. The part mounted on the trunnion is here shown as a wheelI3 and is preferably a ratchet wheel, or a wheel with comparativelysmall ratchet teeth I4 capable of permitting ratcheting in bothdirections, although these parts may be a friction wheel and pawl ortheir equivalent. However, to effect immediate accurate locating of the.sash member 5 in any open position or angle or the step by step movementeffected by ratchet mechanism is preferable. The part movable in thehollow rail I is here shown as a shoe or block I5 spring pressed by aspring I6 against the periphery of the wheel I3 and having ratchet teethI! complemental to the teeth [4, the shoe or block having a stemextending lengthwise of the hollow rail I0 about which the spring iscoiled, the spring thrusting at one end against an internal abutment l8within the hollow rail which has a guide opening for the stem, and atits other end against the shoe or block I5. Manually operable means areprovided for holding the block or shoe I5 from ratcheting movement andhence, holding or looking the sash 5 in its adjusted position. Thismeans is here shown as a rock shaft l9 extending transversely of thehollow rail l0, and having a cam or eccentric 20 thereon arranged tothrust against the end of the stem. The rock shaft has a handle 2| onthe outside of the rail, which handle extends radially relatively to theshaft in order to lie close to the outer face of the rail.

When the sash is raised, and the rock shaft is turned so that the lowpoint of the eccentric or cam is opposite the end of the stem, then thesash member 5 can be turned about its axis as the shoe or block I 5 isthen free to ratchet. When, however, the rock shaft is turned to carrythe high point of the cam or eccentric against the end of the stem, theshoe or block is held from ratcheting movement and hence, the sashmember 5 held in its adjusted position.

As here illustrated, the block or shoe [5 and associated parts, that is,the spring and cam, are a self-contained structure insertable as a unitin the rail Ill, and suitably secured therein, the insert being achannel 25 in which the block slides, and through which the trunnion 8,with the ratchet wheel thereon, extends, and in which the shoulder 18 isformed, and in which the cam shaft I9 is mounted. The insert is coveredby a suitable weather strip 26 coacting with the rail of the sash member5, the weather strip 26 having an opening for a spacer 21 around thetrunnion l0 between the lower rail of the sash member 5 and the insert25. The spacer 21 is here shown as formed with a recess (Figure 2) inwhich a spring 28 is located thrusting at one end against the bottom ofthe recess and at its other end against the insert, the spring taking uplooseness and preventing rattle.

The top rail of the sash member 5 is provided with an insert 29 andratchet mechanism coacting with the trunnion I, which insert 25 andratchet mechanism is similar to the insert 25 in the bottom rail and theratchet mechanism therein, except that the ratchet mechanism in theinsert 29 has no locking means corresponding to the cam 20 and handle2|.

By this window construction, the pivoted ventilating window can beraised and lowered into and out of the lower body, or vehicle body, andwhen in its elevated position, the sash member can be locked in itsadjusted position against unintentional displacement. Owing to theconstruction of the ratchet mechanism, and its relation to the sashmember 5, or the trunnion thereof, it is particularly compact and can belocated in a hollow rail and operable from the outside of the rail bymeans which does not obstruct the raising and lowering of the sash.

What I claim is:

In a window structure, the combination of a suitable body, a window sashcapable of being lowered and raised into and out of the body, the sashincluding a frame having a hollow rail, a second sash pivotally mountedin the first sash on an upright axis and movable about its axis fromnormal closed position into different inclined open positions, means forpivotally mounting the sash member including a trunnion on the sashmember, ratchet mechanism including a part mounted on the trunnionwithin the hollow rail, and a second part coacting with the first partand located in the hollow rail, and manual means operable from theoutside of the rail for operating the second part to hold it engagedwith the first part and prevent ratcheting thereof.
